METAL WINDOW-SASH.

To all whom it may concern:

Be it known that I, JOHN T. LEONARD, a citizen of the United States andof the State of New Jersey, residing at VVoodcliff, New Jersey, haveinvented certain new and useful Improvements in Metal YVindow-Sash, ofwhich the following is a specification.

My invention relates particularly to window sashes which are formed ofhollow sheet metal and consists in certain improvements whereby thesheets or panes of glass may be readily and conveniently insertedtherein and held in position or removed therefrom.

In the drawings Figure 1 is a vertical sec tion of one of my improvedsashes showing the top and bottom rails cut through and the center ofthe side rail broken out; Fig. 2 is a top view of portions of the sashshowing the side rail and middle rail and the fasteners in broken lines,and Fig. 3 is a plan view of one of the fasteners.

Similar reference numerals indicate corresponding parts in all thefigures.

The window sash 1 is formed of a shell of sheet metal, and is providedwith a groove 2 in the sides and bottom thereof which runs into a slot 3above and into the top rail. The top rail is provided with inwardlyinclined flanges 4, 4, upon which rest the complementary flanges 5, 5,of the sheet metal cover, 6, which is pierced at suitable distances toallow the passage of threaded bolts 7, 7, which carry the fasteners 8,8, these fasteners being provided with grooves 9, 9, adapted to receivethe flanges 4, 4, and with projecting portions 10, 10, which are adaptedto enter inside of the top rail so as to prevent more than a. partialrotation of the fasteners 8. Bolts 7, 7, are preferably enlarged attheir lower ends, as at 11, to prevent their being drawn entirelythrough the fasteners 8, 8, and also to give them a broader bearing onthe cap 12 which closes the top of the groove. It will be seen that whenthe metal cover 6, with its attachments, is removed from the top rail,and the slot cap 12 is lifted off, a sheet of glass may be slipped downthrough the top rail into its proper position in the groove 2. The cap12 is then placed over the top groove. The cover 6 is next fitted intoposition on the top rail, the fasteners 8, 8, being turned into theposition shown by the broken lines at the right of Fig. 2, and loweredon the bolts 7, 7, so asto allow them to be passed down between theflanges 4, 4, of the top rail,

when their extensions 10, 10, engage against the inside of the top railand prevent their turning further. The continued turning of the bolts 7,7, will draw the fasteners 8, 8, up against the flanges 4, 4, and clampthem firmly in position, thus securing the cover 6 firmly upon the toprail. At the same time the ends 11, 11, of the screws 7, 7, will beardown upon the slot cap 12, holding it in position over the slot 3, andeffectually preventing the glass from slipping out of the sash inwhatever position the sash may be. In case it is desired to remove theglass at any time, it is only necessary to turn the bolts 7, 7, fromright to left, thus lowering and releasing the fasteners 8, 8, and turiring them so that they may pass up between the flanges 4, 4, when thecover is lifted off. The slot cap 12, can then be removed and new glasscan be inserted in the sash. By this arrangement I secure a sash whereinthe glass can be securely and easily placed and replaced withoutremoving the sash from its position in the window, and in which theglass will be securely held against lateral or vertical displacement.

Having thus described my invention, what I claim and desire to secure byLetters Patent of the United States, is

1. The combination in a metal window sash, of a bottom rail and siderails having a,groove therein, a top rail having a slot through thebottom thereof and an open top provided with inturned edges, a cap forthe top rail slot, a cover for the open top of the top rail, and meansconsisting of a partially rotatable fastener and a threaded bolt passingtherethrough to detachably secure said cover to the top rail by engagingwith its inturned edges and to hold said slot cap in position.

2. The combination in a metal window sash, of a bottom rail and siderails having a groove therein, a top rail having a slot through thebottom thereof and an open top provided with inturned and downwardlyinclined edges, a cap for the top rail slot, a cover provided withinwardlyv and downwardly turned edges, and means consisting of apartially rotatable fastener provided with upturned ends and a threadedbolt passing through said cover and fastener to detachably secure saidcover to the top rail by engaging said fastener with its inturned edges,and to hold said slot cap in position by the end of the bolt bearingthereupon,

with upwardly turned inclined ends, and an extended portion to preventits complete 10 rotation within said top rail.
